Gravity and magnetic survey
WebMay 5, 2013 · Fortunately, in most magnetic survey campaigns these extraneous variations are considerably less effective in distorting effects of subsurface sources than those of the gravity method. Thus, the requirements for auxiliary data and reduction procedures are much less stringent for the magnetic method than in the gravity method. WebThis dataset comprises over 165 000 gravity observations on onshore Great Britain. Most of the surveys were carried out by the BGS but the dataset includes data originally …
